A study was conducted among a smaple of undergraduate students to find the relationship between the number of cups of coffee consumed (x) and level of anxiety (y). The following least squares regression equation was obtained as a result of the study: ŷ = 0.1+ 0.0355¤ The obtained regression equation implies which of the following? Each cup of coffee consumed increases anxiety level by 10.0% Each cup of coffee consumed increases anxiety level by an average amoint of 3.55% Each cup of coffee consumed increases anxiety level by exactly 3.55% Anxiety level increases by 1 unit as a result of consuming 0.1 cups of coffee
